I must be missing a point.

Why does one DeFrag a File or Files?

What would be the situation or circumstance that would warrant Defragging a File by itself? I looked at the description and features of Defragula but I am missing something.

Thank you for educating me in advance.

Because if you defrag only the files you actually use, it is much faster and you don't have to each time defrag the whole drive.

I'd recommend reading the Defraggler documentation for a better understanding:
http://docs.piriform.com/defraggler

There's this Wikipedia article about defragmentation:
http://en.wikipedia.org/wiki/Defragmentation

OK, will look up the links.

Thank you.

OK, great.

BTW, by just looking at DeFraggler's Analysis,
can one know which particular file or files need defragging?

I ask this because there are PCs that I need to manage
but I don't use, so I am not familiar with all the files the user uses.

Than you.

Hi DeeDee2

Yes you can find out which files need defragging. After you analyze drive click on View Files and it will show you a list of files that need defragging.
Than either tick all of them or just highlight them all and than defrag all ticked or all highlighted. You can also click on the blocks once analyzed to learn more about what's going on with your drive.

If defragmenting other peoples systems I'd personally only do a files-only defrag versus a full defrag. A files-only defrag will be done quickly versus a full defrag which could take a very long time.

The Don, Andavari,

Thank you for the explanation and suggestions.
